RESUMO
BACKGROUND: Delays in treatment of head and neck squamous cell carcinoma (HNSCC) are known to increase disease recurrence, generating the need for additional salvage treatment, often with immunotherapy. METHODS: Three treatment metrics were identified: time from diagnosis to treatment initiation (TTI), time from surgery to postoperative radiotherapy (surg â PORT), and total treatment package time (TPT). Financial toxicity was calculated using hazard ratios, pembrolizumab cost, and dosing data for a Veterans Health Administration (VHA) institutional cohort (n = 338) and a standardized cohort (n = 100). RESULTS: Estimated financial toxicity for the VHA cohort was $2 047 407, $316 545, and $1 114 101 for TTI, surg â PORT, and TPT, respectively. Estimated financial toxicity for the standardized patient cohort was $454 028, $544 576, and $1 879 628 for TTI, surg â PORT, and TPT, respectively. CONCLUSIONS: Failure to meet established HNSCC treatment metrics generates significant, yet avoidable, institutional financial toxicity which is particularly relevant to integrated single-payer systems such as the VHA in the modern immunotherapy era.
